Power: inside the dashboard is the main power cable directly from the battery in the back. At least 50A spare capacity according to Lotus.NtflBlueLiz said:Anyone can point me to a good place to pick up the positive side of the battery as well as ground near the front of the Elise ?
Or you could check out the relay and fuse boxes and pick up a reasonably big power feed from there.
Ground: Tricky.. There should be a ground point on the inside of the chassis rail at the driver's side under the service/access panel.
Problem is that this point is incredibly obstructed by the heater box on LHD cars (ground points are not changed on RHD vs. LHD cars), so it's practically impossible to get to without disassembing pretty much the entire front end of the car.
You could splice into some of the ground cables that come from this point though.
As the car is glued you can only really use the driver's side chassis rail as a reliable ground point (in the back there's another one where the engine and battery is attached). All other aluminum chassis parts in the car only have a rivet/glue connection to the ground points, which (obviously) is not very good for conductivity.
